One path I would like to see pursued is multiple\np2pool-esque chains.  Each with their own policy, perhaps with their\nown administrative team.  ie. you could have a fully decentralized\np2pool-like chain, or multiple such chains, each with a stated\npolicy/reward pattern.  Or, GHash/BTCGuild/Eligius could run a\nsemi-centrally managed chain ultimately guaranteed not only by\nprotocol but by administrators' digital signatures.\n\nIn each case, advertising technical attributes about your pool [chain]\npolicy would give nodes the better ability to predict what is in an\nupcoming block.\n\nAnd the flip side of that, such predictions are never perfect.  Need\nto make sure the fallback case, while undoubtedly more costly than the\nFast Path, is not overly painful.\n\n\n-- \nJeff Garzik\nBitcoin core developer and open source evangelist\nBitPay, Inc.      https://bitpay.com/"}
